Motorola Modem Symbols: Explained with States
In this section, I will provide you with ample information on the various lights on a Motorola modem. You will gain an understanding of their behavior in ideal conditions, the potential states, and what steps to take if any issues arise.
1. Power Light
- Meaning: Connected to a source of power
- Ideal Light Color: Solid Green
Different States of Power Light and Their Meanings:
- Solid Green: If you see the power light in solid green, it means the device is connected to a source of power and turned on.
- Blinking Green: If the light doesn’t light up, it either means the power cord is not plugged in properly, there is an issue with the power supply or the power cord is faulty. Ensure the power cord is plugged in tight at both ends (power outlet and the modem) and the supply at the power outlet is stable.
2. Downstream Light
- Meaning: The modem is connected to 1 Downstream channel/bonded channels
- Ideal Light Color: Solid Green/Blue
Different States of Downstream Light and Their Meanings:
- Solid Green/Blue: A solid green or blue on your downstream light shows the internet connection is active. The green light shows your modem is operating on a single DS channel and the blue light shows your device is operating on bonded channels (for high-speed connections).
- Blinking Green: If you see the Motorola modem down arrow flashing, it means it is establishing a single downstream channel for communicating with the ISP.
- Blinking blue: If your modem is blinking blue, it shows the modem is set up to bonded channels.
When the connections are initialized, you will notice the lights flashing for a few minutes. If the light doesn’t turn solid, which signals, there is trouble connecting to the internet. The underlying reason could be anything from service disruption to a faulty device.
Anything in between you can fix by allowing the device to rest and checking for any faulty cables and loose connections.
3. Upstream Light
- Meaning: The modem is connected to 1 Upstream /bonded channel
- Ideal Light Color: Solid Green/Blue
Different States of Upstream Light and Their Meanings:
- Solid Green/Blue: A solid green or blue on your upstream light shows your upstream channels and the internet connection is active. Similar to downstream, a blue or green denotes the type of internet connection and high-speed capability.
- Blinking Green: A blinking green light suggests the ongoing ranging process where the connection is established with the ISP.
- Blinking blue: A blinking blue signals your device is starting channel bonding (high speed) for upstream communication
If the flashing light doesn’t turn solid in a few minutes, it signifies trouble connecting to the internet. Check for loose connections or faulty cables and maintain a steady power supply. Check with your ISP for information on internet outages and maintenance.
4. Online Light
- Meaning: Active internet connection
- Ideal Light Color: Solid Green/blue
Different States of Online Light and Their Meanings:
- Solid Green/Blue: If your online light is stable blue it signals, your device has an active internet connection operating on DOCSIS 3.1 bonded channels. A solid green shows the internet connection is active on DOCSIS 3.0.
- Blinking Green/Blue: You’ll notice the lights flashing along with your US/DS lights when the modem is turned on/reset and the device is initializing the connection.
- If the lights blink blue and green, it could also show firmware update is underway. Don’t interrupt the process and wait for 15-20 minutes for the lights to turn solid.
Once your US/DS lights turn solid, you will notice the online light turning solid. If the light continues to blink, it refers to trouble connecting to the internet. Ensure your cables and coaxial splitter are not faulty.
Power cycle the device, ensure heat ventilation, update the firmware and try a manual reset. If nothing works, time to throw in the towel and call for professional help.
5. 2.4 GHz WLAN

If the lights are turned off, it usually indicates the wireless is not active. Login to the admin portal and check if the band is disabled. You’ll be able to activate the band by changing the toggle buttons or clicking on the check box.
If it still doesn’t turn on, you can try updating the firmware or doing a manual reset before calling in for replacement.

If your device has a 5GHz radio and the light doesn’t turn on, you can check the admin portal for default settings. Turn the radio on and restart the device. If the light remains off, check for information regarding the latest firmware. The last resort is to contact the OEM to claim a warranty and device replacement.
